Algorithm of Fixed Point Iteration Method. Choose the initial value x o for the iterative method. One way to choose x o is to find the values x = a and x = b for which f (a) < 0 and f (b) > 0. By narrowing down the selection of a and b, take x o as the average of a and b. Express the given equation, in the form x = g (x) such that |g’ (x ...2x^{2-1}+6x^{1-1} The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}. 2x^{1}+6x^{1-1} Subtract 1 from 2. 2x^{1}+6x^{0} Subtract 1 from 1. 2x+6x^{0} For any term t, t^{1}=t. 2x+6\times 1 . For any term t except 0, t^{0}=1. 2x+6 . For any term t ...The integral of cos(2x) is 1/2 x sin(2x) + C, where C is equal to a constant. The integral of the function cos(2x) can be determined by using the integration technique known as substitution. In calculus, substitution is derived from the cha...Solve an equation, inequality or a system.
